I have the problem with bad filament change post script. Creality Ender 3. Post-Processing to Switch Filament. The printer completes the layers as desired. Then moves to a coordinate over the print and purges a blob of filament onto the work piece. Then moves to the corner on the build plate (10,1) and starts another filament push. The printer is grinding loudly in the process ... because the head cannot print as fast as the line is asked to move. The printer gives off an audible alarm. Nothing responds (controller or octoprint) and the printer needs a hard shutdown to make it stop. Primary issue is that the printer stops unrequested over the printed item, pushes filament instead of retracting, then moves away to the corner and again instead of retracting pushes to seemingly purge.
